Mxx
Selects a scanner channel
with xx = 01 to 80
MPx
Scanner mode with
x = 1 1-pole, 80 channels
x = 2 2-pole, 40 channels
x = 4 4-pole, 20 channels
NVxxxxxxxxx
Calibration, calibration string transfer
After NV the multimeter expects a 9-digit unsigned integer decimal number
as nominal value for the calibration via the interface. A nominal value must
be transmitted alone, i.e. no other command from the table above may be
contained in the same string. The digital multimeter starts the calibration after
transmission of the nominal value.
NV“ppppppp“
Entry of the calibration 7-digit PIN number
Ix
Contrast setting with x = 0 .... 9
RD?
READ?, reads out the current measurement reading
(esp. used for RS232 interface)
CNx
x = 0 Continuous mode off ( esp. used for RS232 interface)
x = 1 Continuous mode on
5.8 Display Mode
In display mode the computer can output text messages to the display of the
instrument irrespective of other functions of the instrument.
Display mode is switched on with D1. The ASCII characters following thereafter are
written to the display. All ASCII characters for which a segment code is defined in
the ASCII segment table are displayed. All other characters produce a blank (dark)
